Data portability

#1

Hi,

I've never used an OODB, I'm looking for a starting point but a recurrent concern is the Data Portability one. More clear: what options / strategies do I have to export / move my data to another tool, if there is a need to?

One key point of Ojectdb (as far as I had read) is Code Portability (based on JPA/JDO standards), but what about Data Portability?
